Princeton, N.C. — Police are looking for the man they say robbed a BB&T bank branch in Princeton just before 9:45 Thursday morning.

According to authorities, the man, wearing all black including a mask, pointed a handgun toward an office inside the 102 N. Pine St. bank and fired one round before ordering everyone inside to the ground. No one was injured, but police said the robber made off with more than $5,700 in cash.

Following the incident, Princeton High School and Princeton Elementary School were briefly locked down as a precaution, Tracey Peedin Jones, spokeswoman for Johnston County Schools, said.

Authorities said the suspect got away in a vehicle described as a silver 1999 to 2002 Chevrolet Tahoe, with 22 inch chrome wheels and tinted windows.

Anyone with information about the robbery is asked to call police. The North Carolina Bankers Association is offering a reward for information leading to an arrest and indictment in this case.
